The US Supreme Court hears arguments on whether public libraries should be required to filter porn sites on their computers. “The case pits free speech rights against the government’s ability to protect the public from the seamy side of the Internet. Solicitor General Theodore Olson argued that libraries don’t have X-rated movies and magazines on their shelves and shouldn’t have to offer access to pornography on their computers. Librarians and civil liberties groups contend that filters are censorship and that they block a vast amount of valuable information along with the pornography. Some of the justices seemed skeptical of the challenge to the Children’s Internet Protection Act.”
